An injection device assembly including a housing, a syringe, a drive mechanism and one or more sensing systems are described. The drive mechanism advances the syringe from a storage position to an injection position, and a plunger advances the syringe piston from an initial position to a final position. The status sensing system may include one or more main PCB(s) disposed in an end portion of the injection device assembly's housing. The system may determine various parameters related to an operational status of the injection device, including the location of the devices components, an amount of medication remaining in the device, a temperature of the medication, and whether or not the device is properly contacting the users skin before injection. The system may communicate such determined parameters to an external device via a wireless communication link.

A process and a nebulizer for dispensing a consecutively dose of medicament in the form of a mist, comprising: an energy source (ES), an air-conditioning volume, an air outlet fluidity connected to the air-containing volume, an air actuator adapted to release a flow of compressed air through the air outlet at such time as a predetermined ES pressure has been reached in the volume and at least two valve means in communication with the air actuator. The compressed air is released at a predetermined pressure of about 20 to about 100 psig. The valve means controls the actuation of the air actuator such that when a medication is nebulized, a mist distribution of a medication is formed having droplets size in the range of approximately 1μ to approximately 7μ which inhaled by a user at a set of predetermined intervals.

An ultra-thin drug pump may include a micro-body including a drug chamber, an intermediate outlet formed on one upper side, and an aperture formed on the other upper side; a first membrane covering the aperture; a second membrane covering the intermediate outlet and including a drug outlet formed at a position spaced apart from the intermediate outlet; and a magnetic driving part formed on the first membrane to face the drug chamber, and can release a predetermined amount of the drug by an external magnetic field.

An auto-injector apparatus includes a flexible container containing a liquid medicant, a needle communicated with a container, a housing with a container being received in the housing, pump disposed in the housing and positioned to engage the flexible container and expel the medicant from the container through the needle upon relative movement between the pump and the container, and a main drive spring operably associated with the needle to extend the needle from a first needle position wherein the needle completely received in the housing to a second needle position wherein the needle protrudes from the using. The pump may be a roller.

An implantable externally driven fluid delivery system for localized delivery of medical agents and drugs, such as antibiotics, may be provided herein. The fluid delivery system includes a housing that incorporates a filling septum connected to a flexible internal reservoir. The reservoir is connected to a miniature diaphragm pump with coupled magnetic components. The entire fluid delivery system is implantable into a body cavity or surgically formed location that provides for local medical agent delivery. The reservoir is filled via percutaneous injection through the skin into the septum. Fluid delivery is achieved through proximity of the external controller that generates an oscillating or reversing magnetic field suitable to actuate the pump's diaphragm resulting in controlled fluid flow. Once local drug delivery treatment is complete, the controller can be discarded.

Disclosed herein are wound bandages that employ electromagnetic elements to accelerate wound healing and therefore reduce the time that such bandages must be worn. In embodiments, a wound bandage can include self-contained electromagnetic circuitry that can be energized to provide low frequency electromagnetic energy to a wound while the bandage is worn over the wound to promote wound healing.

A medical device for supplying feedback information when implanted in the body of a patient is provided. The medical device is arranged to monitor or control a physiological function or defect in the body of the patient, the medical device comprises: a radio frequency identification (RFID) transmitter arranged to transmit feedback information from the implanted medical device, wherein the RFID transmitter is arranged to receive interrogating signals from an external device and in response thereto transmit feedback information.

A dry powder delivery device may be configured to provide micronized dry powder particles to airways of a user. The device may include a cylindrical container delimiting a chamber containing at least one magnetically-responsive object, a motor external to said chamber, a magnet external to the chamber and rotatably coupled with the motor, and an outflow member configured to direct airflow to a user. The magnetically-responsive object may be coated with micronized dry powder particles, and the motor may be operable to rotate the magnet about an axis. Rotation of the magnet creates a magnetic field that causes the magnetically-responsive object to move in response to the magnetic field and collide with a side wall of the container to deaggregate the dry powder particles and aerosolize the dry powder in the chamber.

The invention proposes a method and a device for needleless injection of liquid into a substrate, in particular of a liquid pharmaceutical or cosmetic preparation into a biological tissue, making it possible in a particularly advantageous manner to reliably inject a liquid completely into the substrate without a needle. In accordance with the invention, this is achieved by a sequential injection, wherein a first partial quantity of the liquid first exits from an outlet nozzle at a very high outlet velocity as a fine liquid jet under high pressure generated in the liquid by means of a impulse shock and enters the substrate and creates an injection channel in the substrate, into which a second partial quantity of the liquid is then introduced at lower pressure and lower velocity. Preferably, the ejected liquid jet is set in rotation around its jet axis before it impinges on the substrate, so that the jet receives a helical movement and thus practically drills into the substrate without splashing away laterally.
